This commentary is by Mark Naud, who is an environmental and land use attorney in Burlington.I have practiced environmental law in Vermont for 30 years, working on land, water and governance issues throughout this basin. I served as chair of the Vermont Citizens Advisory Committee on Lake Champlain’s Future. And I will tell you something easy to forget when you are inside the daily work of environmental protection: What we have built around this lake is genuinely rare, and it works.
